Rituximab,Zanubrutinib in Combination With Lenalidomide, Followed by Zanubrutinib or Lenalidomide Maintenance in Patients With Primary or Secondary CNS Lymphoma

Study Purpose

In view of the synergistic effects of rituximab, zanubrutinib, and lenalidomide and severe complications caused by current standard chemotherapy regimens in Patients for primary or secondary CNS lymphoma, we intend to conduct a prospective clinical study to evaluate the efficacy and toxicity of Rituximab, Zanubrutinib in combination with Lenalidomide. Besides, the efficacy of Zanubrutinib or Lenalidomide in maintenance was also compared.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	18 Years and Over

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT04938297
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	Phase 2
